Y specification of Letters Patent;

Patented Jan. 26, 190e.

To all whom it may concern:

Be it known that I, CLINTON CALVIN EPPS, a citizen of thev United States, and a resident of Southmayd, in the county of Grayson and State of Texas, have invented a new and Improved Cotton-Grin, of which the following is a full, clear, and exact description.

This invention relates to cotton gins and is particularly useful in connection with devices of this class wherein the lint is removed from the gin saws by means of an air blast.

The object of the invention is to provide a simple, strong and durable cotton gin wherein the air blast, by means of which the lint is removed from the teeth of the gin saws, is directed against the same in a particularly effective manner.

The invention consists in the construction and combination of parts to be more particularly described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 1s a vertical cross-section through a cotton-gin embodying my invention; Fig. 2' is an enlarged vertical cross-section of the nozzle by means of which the air-blast is di-l rected; Fig. 3 is a vertical cross-section on the line 3-8 of Fig. 2; and Fig. 4 is a horizontal cross-section on the line 4 4 of Fig. 3.

Like characters of reference indicate oor- Aresponding parts i n all the views.

Referring more particularly to the drawings I provide a su port frame 1, to which is removably secure by means of a' hinge 3,

the gin-breast 2 having a hopper-opening 4 for feeding the cotton into the device. -The gin-breast 2 comprises the usual seed-board 5 and thegrate .6. Mounted substantially parallel to the gin-breast 4 is a shaft 7 upon which is rigidly mounted a'gang of gin saws 8 separated b y spacing .blocks 9. The ginsaws 8 extend partly through the grate 15V into the gin-breast, in the usual manner.

. to the gangof saws.

An air-chamber 10, preferably ot sheetmetal and cylindrical in form, is carried by the 'supporting frame, substantially parallel The air chamber 10 has an integral head 11 communicating inte. riorl i with the chamber and extending towar s the saws. A tube 12 communicating with the air chamber Q1() conducts an air i i. .blast from a suitable blower into the chamber 10, which acts as' distributing means to vconduct theblast through the head 11 to the saws. plurality of nozzles 13 isposed downwardly .At the extremit of the head 11 is a i and having openings 14 discharging in the l direction of rotation of the saws. zles are so arranged that the air is dischargedtherefrom through the openings 14 in a direction substantially parallel to a plane tangent to the peripheries` ofthe saws. The arrangement is such that a nozzle is located between the blades of each adjacent pair of saws of the gang, the opening of the nozzle being adjacent to the teeth of the saw and extending slightly below the same as is shown most clearly. in Fi 2. At the lower edge of each opening of t e nozzles the bottom 15 ofthe same is extended to form alip 16. Mounted upon theslip 16' and extending across the o ening ofthe' nozzle to-the u per ortion of t e same is a uide plate 17 avmg the sides 18 laterally Vdisposed at an angle with each other to form a V-shaped deflecting member adapted to divide the blast from each nozzle and direct the divided blast against the adjacent saw blades, the edge 19 of the delecting member being arra'l'i ed adjacent to the opening. The guidep ate 17 is cut away into recesses 20 above the 'side 18,

The nozto permit a part'of the air to escape from the nozzle undelec-ted, and in aV direction substantially blades. Y

Mounted upon the supporting frame lis an o-take chute 21 arranged underneaththe head 11 and havinglits receiving opening lo;

cated to receive t e lint-char edi air -blaat from the nozzles.

In this way the lint is expeditiously and .I

thoroughly removed from t e teth of the gin saws and forwarded to the off-take chute for removal from the Having thus descri ed my invention, I claim as new and desire to secure by Letters Patent:

sides thereof.

2. In a cotton gin,

parallel to the, plane ofthe saw The off-ta e chute 211 communicates with a condenser 22 to receive of'any usual Y 10,5 1. In a cotton gin, in combination, a saw, and means for directing convergmgalr blasts against the teeth` of sind .sawat thel saw,` and means for directing converging air blasts against the teeth of said saw at the sides thereof, said air blasts being directed substantially in a plane tangential to the periphery-of said saw. f

3. In a cotton gin, in combination, a gin saw, and means for simultaneously directing anI air blast against the teeth of said saw and a second air blast in a direction substantially parallel to the plane of said saw.

4,. In a cotton gin, gin saws, and a nozzle between adjacent saws, said nozzles having means for directing divergent air blasts against said adjacent saws.

5. In a cotton gin, a plurality of gin saws, nozzles between the blades of each adjacent pair of saws, means for forcing air through said nozzles, and means for directing the air from each nozzle in divergent blasts against adjacent saw blades.

6. In a cotton gin, a plurality of gin saws, nozzles between the saws of each adjacent pair, means for forcing air through the said nozzle, and a directing member mounted at 7. In a cotton gin, a pair of gin saws, anozzle mounted between said saws and having an opening discharging in the direction of rotation of vsaid saws, and a guide plate mounted at said opening and having laterally-disosed sides adapted to direct an air blast from said nozzle against each of said saws.

8. In a,cotton gin', a gin saw, a nozzle mounted adj accnt to said saw and having an opening discharginfr in the direction of rotation of said saw, and a plate mounted at said opening and partially obstr cting the same, said plate being adapted to dellcct air from said opening against said saw.

In testimony whereof I have signed my name to this specification in the presence o1" two subscribing witnesscs.
